Krell Industries EVOLUTION TWO MONAURAL PREAMPLIFIER - Manual (Page 56)

Left/Right Channel Orientation
Evolution Two preamplifiers are assembled as left or right channels. Preamplifier
RCA connectors (31, 36, 38, 40) are color coded. Left preamplifier channels are
assembled with white RCA connectors, and right preamplifier channels are
assembled with red RCA connectors.
Right-Terminated Preamplifier Channel
Right preamplifier channels have a unique electrical identity under CAN Link.
When a system with linked Evolution Two preamplifiers is powered on, the system
automatically identifies the right-terminated preamplifier channel, and left/right ori-
entation is established immediately, with no user intervention.
Any right preamplifier channel that is last in a chain of linked Evolution Two pream-
plifiers is referred to as right-terminated. There is only one RG-45 link cable con-
nected to a right-terminated preamplifier channel.
Example. The illustration below shows the preamplifier chassis back panels of
three linked preamplifier channels. There are two right (R) channels and one left (L)
channel. In this configuration, the top chassis belongs to a right-terminated pre-
amplifier channel:
IR, RC5, and RS-232 Data Transfer from a Third Party Controller
In a group of 2 or more preamplifier channels connected via CAN Link, the right-
terminated channel is the transmitter of IR, RC-5, and RS-232 data to the other
linked preamplifier(s), or receiver(s). Always make IR, RC-5, and RS-232 connec-
tions from the third party controller to the right-terminated preamplifier channel.
